H9 33% Sukhoi SU-26MM / hacker A100

[bsipro]

Hey Every One,
here is my latest Project. I saw this plane and thought it would be real cool as a electric.
here is my setup.

Hacker A100 motor
Jeti Spin 200 ESC
Mejzlik 27x12 prop
TT 4"1/4 spinner
5 JR DS8711 servos
Spektrum AR7000 RX
2 A123 2300mAh RX packs
4 5s 4000mAh MaxAmp Li-po's (10s2p = 36v. 8000mAh)
I'm looking to get 5000 - 5500 watt's out of the setup.

the plane is 22lb. with a DA85 and MTW110 can.
the motor /esc / lipo's are 81/2lb. so I should be able to get it to come close to 22lb. around 245 watt's per pound.

FBW4 on RCgroups used a similar setup on a 33% extra here is a link to the thead. with video http://www.rcgroups.com/forums/showthread.php?t=797864

I ordered the Plane Last week (hope to see it next month sometime)
the Hacker A100 sould be here in 2-3 weeks (out of stock)
the Jeti Spin 200 I will have this week
every thing elise is on it's way

any and all coments are welcome

[blucor basher]

Can't wait to see video! Should be fantastic. Please keep us informed.

[Jocke]

The SU-26 is my favorit! good luck with the build.

[bsipro]

I got the Jeti Spin 200 opto and the Jeti Box real nice.
the ESC is HUGE it wieghs 12.3 .oz with conectors and mounting hardware.
the instuctions are not clear on hook up on the battery side. there are 2 + RED wires and 2 - black wires and 1 16g red wire.
when hooking up the batteries I assume that I will use 2 Deans conectors.
each will go to a series jumper. to conect 2 li-po in series.
the question is were dose the small red + wire conect to.(one of the li-po's ?)

[bsipro]

I was right the small red wire conects to the + side of the plug

[fbw4]

The little red wire goes to a negative side of one of your connectors and you need to connect that battery first. Its there to minimize the amount of spark you get from large batteries. Look closely at the ESC pictures in my thread.

Hello bsipro

First connect the negative side of your battery, then the little red wire,
then the big red pair. The little red wire is to kill the spark, caused by
the rapid charging of the caps.
I do not think you should use Deans conectors with that ESC.

6mm bullets are the way to go.

Dave :)

[bsipro]

I looked closer at the picture of the ESC on fbw4 thread. I see that is attached to the - side of the ESC. the instuction that came with the esc had more on the settings not the wiring.

Thanks
any other info would be great.

[bsipro]

I have a bunch of these conectors with some 2/0 cable it's good for 400amps. :D
the plane would weigh about 100lb. LOL :eek:

[bsipro]

I'm going to be using deans plugs, they hold up well. you need to keep a eye on them.

Thanks

[bsipro]

Desert AirCraft sent me some goodies today, I got my Mejzlik 27x12TH prop and Hub drill guide with drill bit and guide pin.
I also cleaned ot my LHS of all there large servo arms. they said my 5-JR DS8711 servos and 2-servo arms will be here in a few days.
Horizon said the plane will be shipping on 3/16 we will see.

[edge5foamy]

This is gonna be cool!

[bsipro]

Hey everyone
The Sukhio is shipping. Hangar 9 has them in stock !!
should be seeing it this week..

[bsipro]

I picked up the servos today. Still no plane
Here is a little I candy

[bsipro]

ok everyone I have a question,
I'm going to run 2- A123 batterys (2p-2300mAh) for the RX / servos. I have read that you do not have to regulate them just plug them in to the RX.
I cant find any spec. on the HD JR switchs. can they handle 7-10amp draws from the Servo's.
and what conector setup (deans - JR in to switch to RX) I see that Fromeco has some nice switchs and Sin city jets has a HD JR style switch with 18g. wire.
any thoughts would be great.

[bsipro]

I got the answer to my question about the RX Battery setup (thanks snap & derlin on FG) Battery to HDJR switch to RX .Im going to use a deans conectors to get the battery to the switch.
I have been watching some of the other forums and it look's like the first batch of sukhio have had some issuses with wing tube being to tight and cracked cowels. mine hasen't come in yet so it. so maybe the next shipment will be better ?,
I did get some more pices in this week. I got my A123 battery's in and built the packs and picked up the JR switches. still waiting for the motor from hacker and the rest of my servo arms, (all on backorder)
need to order the 4.25 Tru Trun Spinner.
It's OK though the feild is still half snow coverd and wet. I might have to put floats on my 27% Extra :rolleyes:

[drstillpatient]

anything new on the build? really interested to see how it performs

[bsipro]

Still wating on the Plane and motor I hope to see it soon, I have all the other parts to finsh it.

[sprice50]

Can you list the cost of all power system components. Motor/esc/packs... Thanks!

I have a DA85 and pipe and would like to compare.

Anyone else have flight video of a similar setup?

[BoneDoc]

This is going to be fun!

[bsipro]

Hey all
I got a call from Hacker motor will be here tomarro, Im keeping a tab. I will put the numbers together

[bsipro]

I got the Hacker A100 today very Impressive, cant wait to get the plane.
here is a picture of the motor.

the cost of the motor and ESC
Motor : Hacker A100 $700.00
ESC : Jeti Master spin 200 $570.00
Total: $1270.00

Lipo's : 4 Max Amp 5s 4000mAh $760.00

Just a note for the gas / lipo argument I use these battery's in 3 other planes

[Z06kal]

BSI bro. Cool build! I'm going to be turning the 29% Wildhare SU to electric in the near future myself. If I were in your shoes I would ditch the A123 packs for the radio system and run CCBEC's instead off your primary power. Then you won't have any worry about charging the A123 pack and would save about 5 ounces. You should be able to run the plane off 3 CCBEC's. With 3 you can do 1 aileron + 1 elevator half for the first 2 and run the rudder and receiver off 1 . You can program the CCBEC to an output voltage that will give you maximum torque and speed at all times. You want to wire the CCBECs 5S2P as it doesn't support higher than 6S. Make sure the ground on all the CCBECs is the same as the ground to the ESC. Also make sure the power is completely independent on all the CCBECs. There is a complete wiring diagram on the CC website. At 5S voltage the CCBEC's are rated 5amps continuous. In this thread http://www.downonthedeckdiscussion.com/viewtopic.php?t=3114&sid=acf61ab81bbb957220873f2f9a0e5fab there is some info on the power demands of a plane like this. Based on that info I would guess about 30-40mah of usage per minute of flight out of your 5S2P pack. THat would put a 10 minute flight somewhere between 300mah and 400mah. So when you land the 5S2P pack that is also running the radio will be 3-400mah lower than the other. Not exactly a big deal when you are flying 8000mah and should be landing with at least 30% reserve capacity anyway. You should shoot Joe Ford at CC an email about how exactly to best to setup a big plane like this. I had a dicussion with him at the AMA convention about running CCBEC in giant scale and he said just a few CCBECs is more than enough to run a big plane like this.

Personally in all the electric planes I have ran a seprate RX pack, I have always found it to be a major inconvenience to worry about charging the primary batteries as well as the RX pack. Some people will argue about better redundency running a seprate RX pack incase the power system fails. I think you can look at it a couple of ways in a big plane like this. If the CCBEC's are soldered directly to the male plugs that connect to the batteries you would need to completely short out your 5S2P 8000 pack to such a high degree that the battery pack voltage drops down low enough to turn off the radio and servos <4v. That is some serious energy being put into something and will likely result in something catching fire anyway. The CCBEC's also eliminate the need for a power regulator as you get regulated, diversified power anyway. Also, it is possible that something in the radio system shorts out enough to drop the voltage of the A123 below radio cut off voltage and turns off the radio system anyway.

[bsipro]

hey all
got the plane today looks great, need a new cowl and wingtubes need sanding.
I will post pictures

[jfetter]

If I were in your shoes I would ditch the A123 packs for the radio system and run CCBEC's instead off your primary power.

Z06kal,

You may want to take a look at Dimension Engineering's VHVBEC's, they support up to 14S and can be wired in parallel with no additional circuitry. They are also switch selectable between 5 and 6 volts, include a led to be able to tell at a glance that they are armed, very nice...

Is that it? You got the plane after such a long wait and not even a display of emotion? :p
what happened to the cowl?

[jfetter]

I would have wrapped it in blankets so it wouldn't get cold overnight ;-)

My precious!

[NumbSkull]

And still no pics!!!!

I would be showing it off like a new child. Everyone at work would be tired of me showing them pictures and talking about it... :D

[bsipro]

Ok,
I got the plane yesterday at lunch time, took it out of the box gave it a hug and went back to work.
when I got back from flying last night I diched the fuel tank thing and mounted the gear, rudder and tail wheel.
after looking at it all day at my shop and hearing everyone tell me that I could put my dog in it and fly him around. I was able to start on it at 5pm (work get in the way all the time)
So this is the what I have done.
Rudder servo mounted / tested
Horzontal Stab wing tubes sanded and mounted
Elevator servo's mounted / tested
I'm working on the wing tubes ( they need sanding )
all the servo's are preped for instation.

[bsipro]

so this is were I'm thinking of mounting the ESC.
Under the motor box were the can would go.
I would beef up the supports under the motor box and open up the tunel for the muffler
for air flow.
I will need to make some 1" stand off's for the motor.

[bsipro]

OK I'm Done for the night. all servo's mounted and tested. canopy and hatch mounted.
tomarro I will mount the ESC and Motor.

[NumbSkull]

Looks Great!!!!

Did the pilot come with the kit, or did you add that?

Is this bird going to be at SEFF? I would love to see it in person.

[bsipro]

the pilot comes with the kit, I'm not going to SEFF I will be working. I'm planning NEAT at the end of summer.
I got the motor mounted and all the soldering done.
I used 6mm x65mm bolts flat washers and 2" 1/2x1/4 nylon spacers. It will get my prop 6"1/4 from the firewall. (use blue thread locker.
I need to mount the ESC and do some detail work I should have it in the air on sunday.

[sun.flyer]

Great looking setup!!

I look forward to hearing your flight report. :)

Tim

[bsipro]

I CA glued 2- 1/2x1/4 Bass wood supports to the bottom of the motor box to mount the ESC on, I will use 1"1/2 stand off's with #4 screws and lock nuts.
here is a picture of were I was planning on mounting the ESC.

[bsipro]

Hey guy's
I just finished the Plane, I came in at 23.5lb. with No spinner call it 24lb. with spinner.
I have all the throws set, CG is @ 7"5/8
programed the ESC. (changed the Little red wire to the - side of the 1st deans )
we are heading up to the field to do some testing.
here are some pictures

[bsipro]

I maiden the SUK,

12s power was unlimited not much more than 3/4 thottle.
50.2 max volts / 117 amps /5,873 watt's / 244 per LB

10s power was more scale type flying
42 max volts / 98 amps / 4,116 watt's / 171 per LB

the plane few great even in 10mph gust of wind, it tracked nice uplines were straight (the wind was blowing me side ways) It did not need much triming, it slowed down real slow, and landing were smooth even in a cross wind.
I got 2-4min,. flights in. Im charging the batterys now so I will post mAh used.
I need a calm day to really see what it can do.
sorry no pictiures I brought the camera but forgot the memory card .
I'm not going to use a spinner look's real good with out it

It's a keeper / selling the Yak (ha!)

[sun.flyer]

Great to hear your maiden went well!! Those numbers look very impressive.

Can't wait to see some video of this beauty flying. :)

Tim

[bsipro]

Hey sun.flyer
I have seen video of you flying, I think you can be in Ithaca in about 6hr. I'll give you the sticks I run the video. :D

[bsipro]

hey guy's
12s pack 4000mAh 4min flight (not all out) 1134mAh used, I think a 7 min IMAC / 4-5min 3D on 4000 mAh

10s pack 4000mAh 4 min flight (not all out) 1149 mAh used.

I'm going to stay with the 12s setup the power is crazy !

[NumbSkull]

Great to hear about the maiden!!!

Great Numbers!! 200+ watts/pound on a plane that size should make for a great flight.

[sun.flyer]

Hey sun.flyer

Oh don't you go tempting me like that. :D

If I can get things to work out how about I take you up on your offer at NEAT this year. :cool:

Tim

[bsipro]

Hey sun.flyer
let's keep in touch.
I'm going to Nall to check it out. (No plane I'll be on my bike) are you going to be there.

[sun.flyer]

Hey sun.flyer
let's keep in touch.


Absolutely. Maybe something before NEAT might pop up to allow us to do this sooner.

I'm going to Nall to check it out. (No plane I'll be on my bike) are you going to be there.

:( Unfortunately not.

Definately a pilgramage I would like to make though.

Hey all,
Just a little update, I have 6 flights on the Sukhoi. (work is getting in the way) the plane flys great. the Hacker A100 performs great on 12s after a 8 minuite flight it is warm to the touch. the spin 200A ESC is cool to the touch. Im realy impressed with the setup It has a lot of power. I had to change the wheels to Dave Brown Lite 4" the H9 3.5" were not cutting it on a grass runway.

[drstillpatient]

need......video......soon :p

Friend Steve Rojecki has the Sukhoi with Hacker and Lipos -he isn't into th e "forums" I will do the good ol ZDZ80 gasser on my Sukhoi- ( because I have it and it works ) but I do have a new ZDZ 1300 watt motor -I am setting up with 8-9 a123 cells and a CC HV 45 ESC and various props .

[duckalliance]

must... see... video....

lovely plane - nice motor too :)

The JETI stuff is just plain awesome

[bsipro]

Hey All,
Just got back from Joe Nall, It is a Must !!, I got to see the Sukhoi with the new A80 Hacker and a Vess 26c prop on 10s 5000 mAh. it is about 1lb. lighter and has great power. I was told that the A80 will be out soon. but very cool setup.
I have a bunch more flights on the suk. I added some vents to get more cooling.(see the pic)
the plane is a awsome with the A100

[bsipro]

hey all,
I got a Vess 27B prop today, I put it on the suk. with 12s my prop speed went from 6,350.RPM with the 27/12th mej. to 6720. RPM with the vess 27B. the amps went down from 58 amps per leg to 52 amps per leg. the motor is running much cooler.

[hornetflyer]

hello bsipro,

im working on a conversion of the suk too....i have the same set up as you do!

ive got all my servos in the plane 8611s on aleirons 8411s on elevators and one 8611 on rudder

not my first biggin but my first electric biggin

the a-100 and spin 170 came in and MAN what a motor!!

any hints on the installation of the motor and esc????
plastic or metal stand-offs?

thanks
paul

[hornetflyer]

also,

im thinking of running flightpower 25c 4 6 cell 5000 mah packs to give me 12s10000 mah...im thinking that should give me 8 min flights.

how did you mount the motor......it looks like the bolt comes from the firewall and threads into the built in x mount on the motor....is this right??

thanks for taking the time to reply to my questions....im sure i have a few more!

paul

[Geoff Dryer]

I saw no mention of a power box in the configuration. Am I correct in assuming that you are powering the servos through the receiver?

[hornetflyer]

im still deciding on using 2.4 or 72.......i have used 7 8411s on one 10ch jr reciever with no problem (knock on wood)........but ive never run 2.4 on anything but a trex 600......would I need a powerbox for 2.4?

[bsipro]

Hey Hornetflyer,
I used bolts though the firewall and nylon spacers (check page 3 for details)
the setup is holding great no flexing. 12s 5000mAh will get you 7 - 8 min flights no problem, great power. go with the vess 27B prop. you will not need a power box with 2.4 just plug the RX batterys. in to RX. the spektrum stuff rocks. i'm using 5 jr 8711 on one reciever, I also saw this plane using 2 BEC for RX power. no problem.

[bsipro]

also mount the esc under the motor box using stand off's check out page 3. it stays real cool. you will see were I opend holes in the cowl and fus. for cooling I my block off the some of the front opening of the cowl to increase air flow over the motor.

Whose model was it (owner /flyer?)

[hornetflyer]

hey bsipro,

how did you come up on mounting the motor in the picture with the paper drawing?

off to the hardware store for some 6mm bolts!

thanks
paul

[bsipro]

richard / it was your pal steve. great guy.
hornetflyer / I made the drawing and off to the hardware store ;)
I also learned that the spin 200 reads 2 digits after 100 amps. so 52 amps would be 152 amps. learning something new everyday. jeti manual is lacking.

So your over 7500 watts???

[steve2972]

The little red wire goes to a negative side of one of your connectors and you need to connect that battery first. Its there to minimize the amount of spark you get from large batteries. Look closely at the ESC pictures in my thread.

Have you got a link to your thread or a picture of the wiring of the 200 esc.? I`ve just bought one of these and still confussed where the small red wire connects :confused: Also do you just solder the 2x pos and neg leads together to make 1 pos/1 neg? This is my first mega esc and the wiring instructions are not clear.Any help much apprciated.

Steve

[steve2972]

I CA glued 2- 1/2x1/4 Bass wood supports to the bottom of the motor box to mount the ESC on, I will use 1"1/2 stand off's with #4 screws and lock nuts.
here is a picture of were I was planning on mounting the ESC.

I want to use bullet connectors,but not sure how the wiring goes,all seems a bit confussing to me.Why are there 2 + and 2 - power leads.Also the instructions say the small anti - spark wire goes to the +side of the pack? :confused: :confused:

[bsipro]

here is the latest
12s 10,000 mAh, 44.4 volts (holding volts) 152amps = 6748.8 watts
I could get more if I used newer batterys.

steve2972
there are 2 sets of leads so you can run 2 or more packs.
you want to conect the wires in this order
1 (-) black wire
2 (+) small red wire (you will here your esc beep)
3 (+) large red wire
you Can add a small red wire with a conector to the (+) side of your pack. so your pack will have two (+)red wires one small and one large.
check out my forum on FG http://www.flyinggiants.com/forums/fg189/26658-h9-33-sukhoi-su-26mm-hacker-a100-3.html (post 33)
I hope this helps.

also the plane without battery packs is 19.5 lb. (if any one wanted to know)

[steve2972]

Hi Bsipro,
So basically if you where using 2 x single packs you could use a black and red wire from the esc for each battery instead of having to connect the 2 batteries in parallel first.Is that right? I`ll be using 4 x 5 s 5300mah packs,2 pairs in series so I could use a black and red wire for each 2 batteries set?

Thanks for the info,

Steve

[bsipro]

hey steve2972
I use 4 6s 5000,
if you go back though the post you can see how i made the conection.

[markepilot]

BSIPRO

Can you tell me the all up weight of your SU-26? Also weight of power system, batts, motor, esc? I'm thinking of using two E-Flite power 160's in tandem on 10s each. Do you think 5500 watts will be enough power?

Thanks in advance, Mark

[Geoff Dryer]

I am also very interested in ganging two motors together for this Sukhoi. If can give details:

http://www.rcgroups.com/forums/showthread.php?t=872197

[bsipro]

the plane is 19.5 lb without lipos
with 12s 8000mAh (4 6s/4000) the plane is 23.5lb
with 12s 10000mAh (4 6s/5000) the plane is 26 lb (heavy batterys)
the plane flys good on 5s better on 6s
the 160 is a good motor I used it in the H9 27% 260 (you had to push the motor to get 2600 watts out of it)
I do not feel that 2 motors are the way to go with all the options on the market with big outrunners. 6000 watts is were you need to be anything less I think the plane will be lacking. check out the new hacker A80. it flys great on 10s in the suk.
hope the info helps

[McFlymaster]

I've got some diagrams and some pics on my qq 102 thread for the SPIN wiring. Have a look here.


Mcfly

[bsipro]

here is a little update,
I found that the H9 27% cap has a real nice alum. tail wheel for $26.00 I ditched the bent wire assembly and mounted the mechined alum. on the stock CF mount you will need to make a longer mounting shaft (I will post pictures later) It works great and looks good to.
also I'm running the new Max Amp 6s 4200 mAh 25c lipo's
the volts are holding @ 43.3v amps are 178 amps, the batterys came down at 90 deg. after a 6 minute flight
Thanks (Josh) Max Amps

[markusvt]

Did the mounting stay good for you? If so, makes you wonder about the complicated set-ups you can buy if a few bolts and standoffs work well?

the pilot comes with the kit, I'm not going to SEFF I will be working. I'm planning NEAT at the end of summer.
I got the motor mounted and all the soldering done.
I used 6mm x65mm bolts flat washers and 2" 1/2x1/4 nylon spacers. It will get my prop 6"1/4 from the firewall. (use blue thread locker.

[bsipro]

hey markusvt
I have about 30 flights and the motor is tight. I have used this mounting setup it works well.

[BingWing]

Very interested in building a similar setup - You mentioned 10s was more scale like but was it ok for 3D still ? How many Watts was your 10s putting out as apposed to the prefered 12s ? Thanks from Australia !

[bsipro]

hey Bing Wing
I was using 10s 20c lipo's so power was lacking. I would say that 3D flying would be questionable. if you had a 10s 25-30c lipo I think you would be good.
with the 10s 20c lipos I was getting around 4100 watt's, the 12s 20c setup I get 5800 watt's, the 12s 25c setup I get 7600 watt's
I saw a 33% H9 Suk with Hacker A80 on 10's TP 25c packs power was very good. It was 1 lb. lighter
hope this helps

[BingWing]

Bsipro - Thanks for the response. Yes, this info helps alot. I am planning on using the plane for IMAC competitions so no real need for all out 3D flying but that said, i do like to fly 3D and think i would be disappointed if it was not really 3D capable. That and good punch out power for low hovering etc. Based on your finding doing the conversion, do you feel the Hacker A80 and 10s 7600 Mah ( FP2 x 3700 5s - 25c ) Would meet my requirements ? I will also be flying with DS 10s 9000 (2x4500 - 22c )

I will be the only one flying with an electric so need to have something that will be equally competitive and that will blow MY sock off ;)

Thanks again

[bsipro]

I'm getting 6min. flights on 8400 mAh packs and using about 5600 mAh the A80-8 on 10s will get you close to 6000watt's with a VESS 26B prop and should work fine the advantage is it is a lighter setup than the A100 on 12s.
AeroModel has the A80-8 in stock and EastRC Has the Vess Props

And you can purchase Vess Props direct from www.vessaero.com, too.

RVess
your right you can buy direct (I was throwing some biz to my bud chris)
I'm looking for a Vess 24b prop for a 50cc yak ?
thanks

I've flown the prototype A80 now for 6 months. The best all around set up is a Vess 26 C. It does good 3D and Imac style flying. For pure 3D a 26 B will work the best and for pure Imac the D is a good prop as it has very good speed at reduce power. The 26 C and D are hard to come by, but if Robert get's enough interest I'm sure he'll get some in. I was able to get a sample of each when Robert first started the 26" size. I don't think he has any at the moment. But check with him for current inventory.

Steve,

Can you tell us what your complete setup is that your running in your Suk.

I'd be interested in seeing what kind of flight times you are getting with IMAC flying. I think it would be interesting to see if I could fly two Sportsmen sequeces on a similiar sized airplane. Thanks

Tim

[BingWing]

Great thanks for the info - very helpful. I have a good amount of FP 5s 3700 25c packs so was hoping to make the most of these but i may be a bit under powered i think.....

[rojos]

My setup beside the A80 includes the Hacker 170amp controller and I normally run two 10S 5000mah Thunder Power Extreme V2 packs that are paralleled thru the controller (total 10K mah). I have tried various props including Menz 26x12 and Menz 26x12 Ultra as well as the Vess 26 b,c,d. I routinly get 6 minutes and put back in roughly 3300 mah per pack for a total of 6600 per flight. I don't normally fly a complete IMAC sequence but a mix of 3D and IMAC manuvers. So I can't say if my setup would fly a complete IMAC sequence from a time stand point. I really doubt you could do two complete patterns unless you had huge packs. I'm sure if you went to something like two 6600 mah packs You would have plenty of flight time for a complete sequence and maybe a little extra to practice a manuver or two at the end. I'm not sure this is a practical way to fly IMAC on a competetive level as the batteries needed would be very expensive. But for demos and sport flying it is a lot of fun and at least proves that electric power is available for those that need it for noise or other reasons.

Any other ? fire away.

Steve,

Thanks for the feedback. Do you have any amp/wattmeter readings on your setup (Thunder Power)?

Hey All
I have a update on the Suk. after seeing Steve fly his suk with the A80 and seeing the 3D hobby crew fly there 35% extra with the A60-18L, and myself flying the H9 Carden YAK with the A60-18L. I wanted to try a experiment.
this is what I did.
I removed the A100 and Jeti Spin 200 from the Suk. and installed the A60-18L in the Suk.
her are some real numbers.

the Sukhoi with A100 and Jeti 200 without Li-po's 19.8Lb

the Sukhio with A100, Jeti 200 and 4-6s 4200 Li-po's 25.8LB

the Sukhoi with A60-18L and CC 110Hv without Li-po's 16.2LB

the Sukhio with A60-18L and CC 110Hv and 2-6s 4200 Li-po's 19.5lb

that is a 6.3LB weight loss.

the plane flew great with the A100 setup 7000 + watts (271+ watts per LB)
very power hungery though.

With the A60-18L it flys great, power feels good, vertical pulls good (not unlimited like before) the setup is 3500 + watts (180+ watts per LB)
the best part is I'm using half the li-po's and get more flights.
the plane still flys better than the H9 Carden Yak.
just one more option for this plane

[bsipro]

one more thing Im using a Xoar 24x12 prop
(a 24" Vess would Rock )
I also had to move the 2 A123 6.6v 2300mah RX packs to the top of the Motor box, the Li-po's moved foward (see picture) and I removed the pilot head to get the CG @ 7-5/8

[Geoff Dryer]

Have you by any chance measured the thrust for this combination?

My Hyperion YAK 180 with the Hyperion motot and Xoar 24x10 provides 27 lb 10 oz thrust on 12S-1P. I assumed that this would not be enough on the Sukhoi.

[BoneDoc]

IF your batt can take it, you can go all the way up to 26x13 (with GOOD throttle management) on the 18L.

[bsipro]

I have not measured the thust, But I will say that it does not feel under powered.
and after a 6 minute flight Im using 3000mah / motor was 115deg. / li-po's 94deg. / ESC 72deg.

the throttle was 1/2-3/4 though all manuvers the plane is very responsive and feels good. I must say that after flying the H9 carden Yak for a few months I have got used to flying with 200 watts per lb.
I flew the plane in a 15mph cross wind and there was more than enough power

the packs that Im using are Max Amps 4200 25c 6s
I have some of the new Max Amps 4200 35c 6s coming
the 25c packs make the A60-18l come alive, the 20c packs seem a little mussy

hey bonedoc. you inspired me to put the Sukhio on a diet. Thanks

[rojos]

Tim,

From my now getting older memory I belive it was around 140 peak. So each battery sees 70 amps. Of course that's at full power in the air as I read it off the Spin Box. I'll try and get another reading and report back but it may be a few weeks as I'm working weekends and the closest field is a weekend only site. When I get them I'll post to confirm the 140.

Steve

[NumbSkull]

The 18L is a great little motor, and can take a lot of abuse!

[bsipro]

Rojos,
what is the weight of the Sukhio without Li-po's and what is the weight of the H9 extra 260 without Li-po's

Numbskull
the 18L is a proven work horse i'm interested in the A80-8 for the suk. the key is the weight, the A100 on 12s is a great setup but 4- 6s li-po's is 6lb's. when I first did this setup I was using 10s-20c li-po's the plane was a little lighter but the li-po's were not up to the task. with a big motor like the A100 you need 25c or better.
I feel the plane flys better at 19.5lb

I will be heading out to the field today I will do some more testing.

[bsipro]

hey everyone
I got 4 flights in on the sukhoi with the A60-18l this weekend - it would be nice to get 4500 watt's with the 19.5lb setup. it comes down to battery weight and mAh

the A60-18l is back in the Yak and the A100 is back in the Sukhio
I think that the A80 is the way to go on a 33% plane you can save a little weight and get good power

[BoneDoc]

Bsipro,

congrats on your weight loss :D.

A good motor to consider is the GR 70. That's be a great match for what you have already. On 23x8, amp draws are reasonable, and at 24x10, it'll really hauls!

[BingWing]

BoneDoc - GR70 ? Dont know it....

Bing,

I've got a GR70 as well. It's been in my 3DH 87" SHP, but will go in an 89" Slick soon.

Awesome motor... VERY powerful!

[BingWing]

Looks great - Nice video Josh... I may consider this motor. Will look into it.

[bsipro]

hey everyone
I recived a package from hacker today. it is a A80-8 motor. I installed it in the Sukhoi
here is the numbers:
Hacker A80-8 /Jeti spin 200 ESC / Xoar 24x12 prop
18lb. without batterys
21lb. with (2) 6S 4200 35C Max Amps li-po's
142 amp @ wot
6100 watts @ wot
6300 prop RPM
3300 mAh - 6 minute flight
pack 92 deg. @ 55 deg. AT
motor 120 deg. @ 55 deg.
the fight was a mix of pattern / vertical uplines
I think that this is the setup for this plane. At 21lb. it flys great. I never had to go past 1/2 throttle I did not feel the need for anthing more. I have a 24x10 Xoar prop coming from 3D hobby. I will post data with that prop.
with (2) 6s 5000mAh you could get 6-7minute flight.
